Check chains are not twisted before hooking
on. When hooking on to the barrier, make
sure the hook is around the bar that runs
across the slot.
NEVER HOOK ONTO THE
SHEET STEEL DIRECTLY
. Make sure the
hooks face outward. I.e. the open side of the
hook nearest the end of the barrier.
Avoid overloading chains. This is particularly
easy to do by snatching the chains, as when
turning the barrier over.
A chain which has been overloaded can break at
any time. Inspection cannot detect imminent
failure. A chain break can kill. Report any chain
that has been overloaded - it must be replaced.
When loading barrier on to trailers generally use
the chains at equal length. This will give the
barrier a slight slope down to the male end.
Terminal end sections are heavier at the
terminal end. Shorten one chain by about six
links to get a more even centre of gravity.
Barrier where the central joint has been angled
to follow a curve will not lift level with a two leg
chain. Where the angle is more than 1° - 2° it is
advisable to use 2 two leg chains on the crane
hook. One two leg chain will need to have 3
metre legs, both with shortening clutches. The
other two leg chains will need to have 6 metre
legs, both legs with shortening clutches. Both
chains need to be rated at least 1.4 tons at 45° -
60° to vertical.
Hook the 3 metre chains to the lifting points
nearest the bolted joint and use the 6 metre legs
for the outer lifting points. Adjust chain length
for even lifting but keep the angle to the vertical
of the outer chains less than 60°.
Ancillary Lifting Devices
There are various alternative lifting devices that
can be used with BG800. See the
Photo Example
section at the end of this manual for
illustrations.
Note: Ensure the lifting device used is compliant
with local laws and regulations.
Please contact Highway Care for further
information.
